SNAP-BAND FOR MOLDS.

To all whom it may concern:

Be it known that I, CHARLES H. GREEN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Snap-Bands for Molds, ofwhich the following is a specification.

My invention relates to an improvement in snap-bands for molds, and moreparticularly in a cheap and eflicient reinforcing of the flanges.

The object of the invention is to improve upon the construction ofsnap-band, forming the subject-matter of U. S. Patent No. 896,379,granted IVilliam Hales, Aug. 18, 1908.

The features of my invention are more fully set forth in the descriptionof the accompanying drawings, forming a part of this specification, inwhich Figure l is a perspective View of the improvement. Fig. 2 is asection on line as, m, Fig. 1. Fig. 3 is a section on line a, a, Fig. 1.Fig. 4 is a plan view of the blank from which the brace is formed.

1 represents the snap-band, substantially as shown in the Haless patent,that is, a rectangular frame 1 is formed of sheet metal, bolted togetherat the corner 2, to form a hollow square band. The upper and lower edgesof the band are formed with the outwardly extending flanges 3, which atthe corners are split, so that their adjacent edges form a V-notch, asillustrated in the dotted lines 4, Fig. l. The flanges not onlystrengthen the band but form the handle for convenient manipulation.

The object of my invention is to reinforce the flanges at the corners inorder to 'make a contiguous flange, practically integral, without anysharp edges being exposed. To accomplish this, I form a blank 5 in theshape of a cross, formed with the rivet holes 6. This cross is bent uponitself, along the diagonal lines 7, so that the arms of the cross lieupon one another in the shape of a rectangular brace 8. This crossedblank is bent upon the flanges atthe corners and secured by rivets, theline of folding extending across the gap formed by the separated edgesof the flanges 3.

Patented Nov. 8, 1910 Serial No. 570,855.

The band thus constructed is very cheap, durable and the flanges arepractically integral. At the same time, this attachment of the braceadds to the appearance of the band and covers up any sharp corners,which would be objectionable if left exposed.

Having described my invention, I claim l. A snap-band for moldscomprising a frame, composed of walls formed of a single strip of sheetmaterial, the edges being bent outwardly forming flanges separated atthe corners, in combination with a flange brace for said corner flanges,comprising a crossbent upon itself to form a rectangular member securedto said flanges, one at each corner.

2. A snap-band for molds comprising a frame composed of side walls, withthe edges thereof bent at right angles forming flanges in combinationwith a flange corner-brace comprising a U-shaped braceplate with itslimbs corresponding in outline with that of the flanges and overlappingand secured upon both sides thereof.

3. In a snap-band for molds, comprising side walls and edge flangeextensions, a reinforcing brace for said flanges at their opposing endsformed of a cross of flexible material bent upon itself at the diagonalline into a rectangular structure, adapted to overlap and be secured tothe flanges upon each side thereof.

4. In a snap-band for molds, of side walls and edge flange extensionsthereof, a flange reinforcement at the intersection of the walls,comprising a U-shaped plate with its limbs extended to overlap andsecured upon the surfaces of two wall flanges.

In a snap-band for molds, of side walls and edge flange extensionsthereof, a flange reinforcement at the intersection of the walls,comprising a bent piece of material overlapped and secured to theflanges at a wall intersection, and of flange outline.

In testimony whereof, I have hereunto set my hand.

CHARLES H. GREEN.
